CanDo® high quality latex resistive exercise tubing has been used in clinics for rehabilitation, conditioning and training since 1987. It has become a staple of many physical therapy and athletic training programs. CanDo® exercise tubing is an economic solution for upper and lower body exercise. It is lightweight, portable and durable. Effective when used alone, or with handles and anchors. Exercise tubing is color-coded according to resistance. Simply unroll desired length of exercise tubing and cut with scissors. CanDo® is licensed to use the Thera-Band® color sequence so resistance level is easily identified. Tubing is available in 8 resistance levels. Levels range in order of strength from least to greatest resistance: tan, yellow, red, green, blue, black, silver, gold. CanDo® low powder exercise tubing is made of natural rubber latex, which may cause allergic reactions. For those with latex sensitivities, there are latex-free alternative offerings of CanDo® exercise tubing. 100' dispenser roll - Red - light.
